i will check the plugs tomorrow

and i have no. check engine lights....the bulb works i checkd on start up

Did you actually check for codes? Very few stored diagnostic errors cause the check engine light to light up and stay lit.

As for air filters... If it's anything like the HKS then congrats, you've just bought a box of hype!

Do research, buy smart fix less... The only two aftermarket air filters I trust to run in my car are Apex'i Power Intake and AEM's DryFlow.

I don't know how that filter compares and I am biased.

its pretty good the sponge is interchangeble ....i got it with a greddy turbo kit i had for my acura.....

Sigh.... I don't care if it's got lights on it... if it doesn't filter well or has a reputation for caving in as it loads up it's still trash.

I'm not saying it's a crap filter, I'm just saying you should do some REAL research before committing your engine and turbo's survival to it's reliability.

If you're running stock boost and your ambient temperatures have been reasonable your car should run fine on 87 or 89 octane... unless it's old gas

Now, did you check for error codes?

jdmmilhouse · 11-05-2009, 05:58 AM

lol......i guess its better then the autozone racing filter....lol.....but anyway i will check for stored codes tomorrow b4 work.....
